The White Dog with a Complex Health Profile
West Highland White Terriers — affectionately known as Westies — are among the most recognisable dogs in Britain. With their bright, inquisitive eyes and confident bearing, they project an image of robust good health. In reality, Westies carry a genetic predisposition to several serious conditions that can significantly affect their quality and length of life. Three deserve particular attention from every owner: Westie Lung Disease, allergic skin disease, and Craniomandibular Osteopathy.
Westie Lung Disease: A Serious Pulmonary Condition
Westie Lung Disease, formally termed Pulmonary Fibrosis or Idiopathic Pulmonary Fibrosis (IPF), is a progressive and ultimately fatal respiratory condition seen almost exclusively in West Highland White Terriers. It involves the gradual replacement of healthy lung tissue with scar tissue, which reduces the lungs' ability to transfer oxygen into the bloodstream. The cause is believed to be a combination of genetic susceptibility and environmental factors, though the precise mechanism is not yet fully understood.
Signs and Progression
Most affected dogs begin showing symptoms in middle to older age, typically from seven years onwards. The earliest sign is usually exercise intolerance — a Westie that once kept pace on walks begins to lag behind, tire quickly, or breathe noisily after minimal exertion. As the disease progresses, owners notice a persistent dry cough, rapid or laboured breathing at rest, and sometimes a crackling sound when a vet listens to the lungs. There is no cure, and the condition worsens over time.
Diagnosis and Supportive Care
Diagnosis is typically confirmed through chest radiographs, CT scanning, and lung function assessment. A veterinary specialist in respiratory medicine can provide the most accurate evaluation. While there is no treatment that reverses fibrosis, supportive care — including bronchodilators, anti-inflammatory medications, and carefully managed exercise — can help maintain quality of life. Avoiding smoke, dust, and other airborne irritants is important for all Westies, and especially so for those with early lung changes. Owners of middle-aged Westies should raise any respiratory concerns with their vet without delay.
Skin Conditions: The Westie's Lifelong Battle
Skin disease is arguably the most prevalent health complaint seen in the breed. Westies are highly susceptible to both atopic dermatitis and Malassezia dermatitis, a yeast-related skin infection, and the two conditions frequently occur together, compounding the misery for the dog and the management challenge for owners.
Atopic Dermatitis
Atopic dermatitis in Westies typically presents as intense itching affecting the paws, face, belly, and ear canals. The skin may appear red, thickened, and darkened in chronic cases. Many Westies develop recurrent ear infections as a secondary consequence of the underlying allergy. Environmental allergens such as grass pollen, house dust mites, and mould are common triggers. Symptoms often begin in the first two years of life and persist throughout adulthood.
Epidermal Dysplasia and Malassezia
Some Westies develop a condition called Epidermal Dysplasia, informally known as "Armadillo Westie Syndrome," in which chronic inflammation leads to grotesquely thickened, hyperpigmented, and greasy skin over large areas of the body. Malassezia yeast proliferates readily on this abnormal skin, worsening the odour and discomfort. Antifungal shampoos and systemic antifungal medication, alongside immunomodulatory therapy for the underlying atopy, form the basis of management. This is a complex, lifelong condition requiring specialist dermatological input.
Craniomandibular Osteopathy: A Condition of Young Westies
Craniomandibular Osteopathy (CMO) is an inherited bone disease that affects the skull and lower jaw of growing puppies. It is seen across several terrier breeds but is particularly associated with Westies. Abnormal bony proliferation occurs around the jaw and, in some cases, the base of the skull, causing significant pain during eating, yawning, and mouth opening.
When It Appears and How It Presents
CMO typically develops between three and eight months of age. Owners notice that the puppy appears reluctant to eat, drops food, or cries when attempting to chew. The jaw may feel swollen or rigid. In more severe cases, the tympanic bullae (bony chambers around the ear) are involved, causing additional discomfort. Diagnosis is confirmed through skull radiographs, which reveal characteristic irregular bone deposits.
Prognosis and Management
The good news is that in most cases, CMO ceases to progress once the puppy reaches skeletal maturity, usually by twelve months of age. The bony proliferations may then partially regress. Supportive treatment with anti-inflammatory pain relief during the growth phase is essential to maintain nutrition and welfare. In severe cases where jaw function is permanently compromised, the long-term prognosis is more guarded. A DNA test for CMO is available and recommended for all dogs used in breeding.
Preventive Measures and Ongoing Monitoring
- Purchase Westie puppies only from breeders who health-test for CMO and can evidence clear results.
- Monitor your Westie's breathing from middle age onwards and report any change in exercise tolerance to your vet promptly.
- Keep your Westie away from tobacco smoke, dusty environments, and strong chemical fumes.
- Book a dermatology referral early if skin problems are recurrent or severe — do not wait for the condition to become established.
- Use veterinary-recommended shampoos consistently during skin disease flare-ups; frequency and product choice should be guided by your vet.
- Feed a balanced, age-appropriate diet and maintain a healthy body weight to reduce inflammatory burden.
- Attend annual veterinary health checks and raise any concerns about appetite, breathing, or skin changes at each visit.
Westies are characterful, spirited dogs that bring enormous pleasure to their owners. With attentive care, early veterinary intervention, and responsible purchasing decisions, many of the conditions outlined above can be managed effectively. Always consult a qualified veterinary surgeon for any medical concerns relating to your dog.
